Description

technical field [0001] The invention relates to the technical field of electrical heat dissipation, in particular to a heat dissipation device and method for a flameproof power-saving speed regulating device used in mines. Background technique [0002] At present, the equipment in coal mines such as belts, winches, scraper machines, shearers, fans and water pumps all need motors to drive, and when the motors are driven, they need to save power and adjust speed, so mines are used. Use a flameproof power-saving speed control device. [0003] However, the power module of the mining explosion-proof power-saving speed control device will lose heat when it is working. In this way, while meeting the explosion-proof requirements, heat will accumulate in the explosion-proof casing, increasing the temperature rise and affecting normal work. [0004] In view of this situation, the usual solution is: use a heat pipe radiator to dissipate heat, that is, install the heat pipe radiator on...

AI Technical Summary

Problems solved by technology

[0003] However, the power module of the mining explosion-proof power-saving speed control device will have heat loss when it is working. In this way, while meeting the explosion-proof requirements, the heat will accumulate in the explosion-proof casing, increasing the temperature rise and affecting normal work.

[0004] In view of this situation, the usual solution is: use a heat pipe radiator to dissipate heat, that is, install the heat pipe radiator on the back door of the explosion-proof enclosure, and then install the power module that needs to be dissipated on the heat dissipation substrate, so that although it can also achieve heat dissipation Purpose; however, when the power of the explosion-proof power-saving speed control device for mines is above 200KW, the size of the heat pipe radiator is no longer suitable for further increase, so when the power is increased, the heat dissipation effect will also be reduced; and the inside of the explosion-proof enclosure Power modules, reactors, control transformers and other electrical appliances that generate a lot of heat have a high ambient temperature. This part of the heat cannot be consumed by the heat pipe radiator, so it will affect the temperature rise inside the explosion-proof enclosure and reduce the life of components.

[0005] To sum up, in the process of realizing the present invention, the inventor found that there are at least defects such as poor heat dissipation effect and short service life in the prior art
